Occupational health risks of barbers and coiffeurs in Izmir

The objective of this study was to examine self-reported occupational health risks and health complaints of barbers and hairdressers. A total of 1284 individuals from 300 workplaces in Izmir participated in this study. The workers completed the questionnaires during their training in occupational health. Self-reported symptoms were allergy: 35% and musculoskeletal symptoms: 32%. The frequency of allergy complaints was found to be signifi cantly higher in older individuals and in women. Allergic complaints were more frequent in i) those having history of allergy, ii) in the group where the use of protective clothing and gloves was lower, iii) in smokers and in those who found ventilation in the workplace to be inadequate. Only 41.2% reported that they used gloves and 15.2% reported the use of protective clothing within the last month. It appears that poor occupational factors in barbers’ salons and exposure to hairdressing chemicals bring about health problems of the hairdressers.


INTRODUCTION
Barbers and hairdressers are subjected to various occupational health risks.Problems such as poor posture, mechanical load on the joints, prolonged standing, longer working hours, missed meals, not taking breaks during working, as well as being subjected to physical factors such as noise and higher temperatures are important occupational health risks for these people. [1,2]smetic products such as shampoos, creams, hair dyes, sprays, and hair conditioners that contain hundreds of chemicals, are being used in barbers' and hairdressers' salons.[26][27][28] The aim of this study was to examine self-reported occupational health risks and complaints of barbers and hairdressers.

MATERIALS AND METHODS
This cross-sectional study was carried out in Izmir province on the Mediterranean coast in 2006.Male and female hairdressers and beauty parlors located in metropolitan counties in the heavily populated central part of the city were included within the scope of this study.Among these, 1284 individuals (workplace owners, shop masters, assistants, and apprentices) from 300 workplaces registered to the Barbers and Hairdresser Trade Corporation of Izmir participated.
Individuals were asked to complete survey forms using the self-report method.Questions asked aimed to identify gender, age, occupational position, and length of time spent in this occupation as well as to collect information concerning workplace conditions (area of the workplace, number of employees, ventilation characteristics), occupational practices, substances used (hair dye, spray etc.), frequency of exposure to chemicals, use of gloves, presence of any painful disorder, presence of allergic symptoms, personal and familial allergy history.Questionnaires were handed out during a training program and were completed by the participants.
The data of the study were evaluated with SPSS computer program, version 13.0.

RESULTS
The mean age of the participants was calculated as 29.44 ± 10.29 years (range: 12-77 years) and 9.3% of them were younger than 18 years old.Over half (59.9%) were males and 40.8% had elementary or lower education levels.The mean number of years of experience in this occupation was 12.88 ± 9.28 years (range: 1-55 years).
Of the participants, 56.1% were salon and parlor owners and out of the workplaces, 15.1% had first class, 53.3% second, and the remaining third class barber status.The mean number of customers was 19.20 ± 14.07 (range: 1-100); 12.0% of the workers stated that they performed manicures/pedicures and other beauty processes, 59.5% performed hair processes, and the rest performed all types of work.
The average area of the workplace was 54.77 ± 55.33 m 2 (range: 8-450 m 2 ).It was reported that all the workplaces were window and/or door-ventilated.Air-conditioning was used for heating and cooling in the majority of the workplaces (70%).Most (82.7%) of the workers stated that they found the ventilation of their workplaces to be adequate.Over half (54.3%) of the workers were smokers and all of them, except for five workers, stated that smoking was allowed in their workplaces.
The question related to chemical usage status was answered only by 391 individuals [Table 1].The use of hair colorings and hair spray were most common, but daily mean usage was lower.On the other hand, the percentage of employees who used shampoos was not high although mean usage was higher.
Only 41.2% of these workers reported that they used gloves and 15.2% had used protective clothing within the last month.It was determined that 4.4% practised dry air sterilization and 3.4% allowed their customers to use their own equipment.The vast majority (80.9%) reported that they used an ultraviolet sterilization device whereas others preferred to wash their equipment with soapy water (9.2%), wipe it with alcohol (41.7%), or to immerse it in a disinfectant chemical (12.7%).Only one-third of these employees washed their hands before and after each process.
When the respondents were asked to identify any discomfort in the past 12 months, 35.0%stated that they had at least one allergic complaint.Nearly 32% all in the groups complained of musculoskeletal discomfort; among these, back pain (27.4%) and lumbago (25.5%) were the most frequent.The participants reported some other health problems: headaches (5.8%), varicosis (15.5%), and fungal infection (1.1%).specify the causes of the allergy-the vast majority consisted of cosmetics and dust allergies.The prevalence of allergic symptoms is seen in Table 2.The most frequent symptom was watery eyes.In older individuals (chi-square: 18.462, P < 0.001) and in women (chi-square: 14.084, P < 0.001), the frequency of allergic complaints was found to be significantly higher.Allergic complaints were more frequent in i) those having a history of allergy (chi-square: 75.02,P < 0.03), ii) in the group where the use of protective clothing and gloves was lower (chi-square: 8.06, P < 0.001), iii) in smokers (chi-square: 10.693, P < 0.005), iv) and in those who found the ventilation in the workplace to be inadequate (chi-square: 26.27, P < 0.0001).It was not found to be related to the number of years of service.Allergic complaints were infrequent only in those performing manicures, pedicures, and beauty care (chi-square: 6.578, P < 0.037).The mean number of customers and the mean area of these workplaces were not found to be related to the frequency of allergic complaints.

DISCUSSION
This study examined the occupational health risks of individuals working in barbers' and hairdressers' salons in Izmir.The daily use of cosmetics containing chemicals was found to be considerably high.On the other hand, it was found that workers did not use measures that would reduce their exposure to these chemicals.General window ventilation was used for the ventilation of these workplaces and local ventilation does not exist in any of the salons.Studies have already proposed that some complaints may increase with inappropriate indoor ventilation. [2]The rate of exposure to chemicals could be reduced by improving ventilation.It has been reported that although individual chemical exposure rates are low, concurrent exposure to multiple chemicals was not taken into consideration.Exposure rates have been shown to increase in smaller and busy workplaces.It is recommended that both the sections where dyes are prepared, besides the whole workplace, should be ventilated. [6,7,10]alth risks related to exposure to environmental tobacco smoke are well recognized.The workplace is the primary source of exposure to environmental tobacco smoke among nonsmoker adults. [20]The authors of this study found that the prevalence of the smoking habit was higher in these workers than in those of other sectors.It has been reported that 34.6% of Turkish adults are smokers. [30]The law prohibiting smoking in closed areas in Turkey was put into effect on 19 May, 2008, so it was not yet in effect when this study was carried out.Smoking in the workplace and in public places was common until the introduction of a comprehensive antismoking law in May 2008.
It has been identified that barbers and hairdressers do not pay sufficient attention to the use of protective clothing and gloves, which are highly important for skin protection and exposure prevention.Our study, like others, [6,7,16,19,31] found that gloves are often not used during the washing of customers' hair.
The overall low use of gloves demonstrates that these workers are poorly protected from biological factors as well as chemicals.In addition, this study also found that sanitation and sterilization of equipment used in workplace, hand-washing, and the wearing of protective clothing were not satisfactory.6][27][28] It was determined that there were more rhinitis, ocular symptoms, and respiratory tract complaints in barbers and hairdressers than in the general population. [32,35]In this study, 35% of the participants had at least one allergic complaint.Some studies have reported a lower frequency of symptoms than expected, which could be attributed to the fact that those with impaired health quit their jobs. [19]In agreement with other studies, [32,36] our study did not find any relationship between the number of years in service and the frequency of symptoms, which may be interpreted as a "healthy worker effect."In Turkey, people begin this occupation at early ages and these salons have a high staff turnover.It has been reported that the risk of having to quit the job due to an allergic disease was > 20% among hairdressers. [37] this study, an increase in the frequency of complaints was found in those having an atopic history.Leino et al. found that the risk of emergence of occupational respiratory tract and cutaneous complaints was three times higher in atopic individuals. [38]wever, like other studies, [35] our study found fewer symptoms in smokers.
Less than half (32.1%) of the individuals interviewed in our study had muscle-skeleton complaints, a finding that was consistent with the findings of other studies. [1,7]iomechanical, organizational, and psychosocial factors have been proposed to play a role in these complaints due to .theload and coercion on the shoulders, wrists, and other joints, which could be reduced by ergonomic hand devices. [1]though this study covered a larger sample in Izmir, the limitations of this study included the lack of clinical examinations and a dependence on self-reporting by the participants.Recall bias might be a problem in survey studies.Besides, a study design which will establish an association between reported complaints and occupational health risks, has not been formulated.No inhouse observations were preformed; the data in this study were collected during an occupational health seminar directed at this sector.
Hairdressers and barbers are mostly at an increased risk of developing cutaneous, respiratory tract, musculoskeleton system, and blood-borne diseases, hence, occupational measures should be implemented to lower these risks. [6,7]Awareness should be built in these workers about the hazards of the chemicals they could be exposed to and atopic individuals should be warned about the risks involved in picking this occupation. [5,10,11]It has been reported that the frequency of occupational cutaneous diseases decreased in Northern Bavaria through occupational health training in Germany. [39]e environment of the workplace should be safe: improving the ventilation, replacement of cosmetics containing hazardous chemicals with other cosmetic products, production and use of less hazardous cosmetics, and imposition of legal sanctions in this regard are advised. [10] has been suggested that success can be achieved in the use of safer products by regulating the use of cosmetics which contain chemical substances. [5]ere are occupational apprentice centers in Turkey for the occupational training of hairdressers and barbers.Younger people who graduate from elementary school (i.e., who have completed an eight-year basic education] and who are younger than 19 years of age, can work in a workplace with social security while taking courses in these places.During this education, they receive training concerning occupational health risks.Hairdressers and barbers take their licenses from the local municipality according to the "Regulation related to Permission to Open and Run a Business for Sanitary Enterprises".However, inspections and legal arrangements are not sufficient; the Turkish Barbers and Hairdressers Federation should disseminate guidelines related to the work of barbers and hairdressers.
